NOTE
Changing the coolant should be done by
an Authorized Mazda Dealer.
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year―at the beginning of the
winter season―and before traveling where
temperatures may drop below freezing.

Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.

The coolant should be at full in the
radiator and between the F and L marks on
the coolant reservoir when the engine is
cool.

If it is at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to F.
Securely tighten the coolant reservoir tank
cap after adding coolant.
CAUTION
 Radiator coolant will damage paint.
Rinse it off quickly if spilled.
 If the “FL22” mark is shown on or near
the cooling system cap, use of FL-22 is
recommended when replacing engine
coolant. Using engine coolant other than
FL-22 may cause serious damage to the
engine and cooling system.

If the coolant reserv oir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.

replacement could cause an electrical
shock or a short circuit resulting in a
fire.

a soft cloth soaked in clean water and
thoroughly wrung out.
If some areas require further cleaning, use
the following procedure:
1. Wipe the soiled area with a soft cloth

The dust-proof sheet has a coating. When
cleaning, do not use a hard or
rough-surface cloth, or cleaning detergent.
In addition, if a chemi

If the windows become covered with an
oily, greasy, or waxy film, clean them with
glass cleaner. Follow th
e directions on the
container.
CAUTION
 Do not scrape or scratch the inside of the
window glass. It could damage the
thermal
filaments and the antenna lines.
 When washing the inside of the window
glass, use a soft cloth dampened in
lukewarm water, gently wiping the
thermal filaments and the antenna lines.
Use of glass cleaning products could
damage the thermal filaments and the
antenna lines.
▼ Cleaning the Floor Mats
Rubber floor mats should be cleaned with
mild soap and water only.
WA R N I N G
Do not use rubber cleaners, such as tire
cleaner or tire shine, when cleaning rubber
floor
mats:
Cleaning the rubber floor mats with rubber
cleaning products makes the floor mats
slippery.
This may cause an accident when
depressing the accelerator or brake pedal
or when getting in or out of the vehicle.
After removing the floor mats for
cleaning, always rein stall them securely
(page 3-49).
